BACKGROUND OF THE INVENTION

1. Field of the Invention

The invention is in the area of means for improving the process of draining and washing ostomy pouches.

2. Description of Related Art and Design Considerations

Drainable pouches are being used by people who underwent ileostomy also referred to as ostomy. Ostomy is the construction of an artificial opening from the ileum through the abdominal wall, permitting drainage of the contents of the small intestine. The drainable pouch is attached to the abdominal opening and collects the discharged waste drained from the small intestine. Every few hours the pouch is filled and needs to be drained. Usually these pouches have the shape of a bag and are made of flexible material such as plastic sheets. The pouch's inlet is attached to the abdominal opening (also called stoma) usually by an abdominal inlet coupling which can detachably secure the washable pouch to an abdominal adhesive faceplate. The abdominal adhesive faceplate has on its proximal side an adhesive layer called skin barrier surrounding a central opening. The adhesive layer of skin barrier enables to adhere said abdominal adhesive faceplate to the user's abdominal skin surrounding the user's stoma. There is a second type of drainable pouches which have an abdominal inlet which is connected directly to the abdominal adhesive faceplate without a detachable coupling.

Prevalent pouches also have an outlet from which the pouch is being drained. This outlet is sealed during discharged waste accumulation and can be opened for drainage and re-sealed afterwards. When the user drains the pouch, the user has to open the outlet and to squeeze the pouch in order to drain it. The inventor personally had ileostomy and had been using these pouches for few years. Users of ostomy pouches are experiencing a major difficulty in the draining process. Since the discharged waste is highly viscous and sticky, it adheres to the inner walk of the pouch and draining it requires a lot of squeezing. Even after a lot of squeezing the pouch is not completely emptied and remains with considerable residue inside. To alleviate this problem, the inventor developed a washing and draining procedure in which the user is adding water to the pouch through the draining outlet. Next, the user mixes the discharged waste with the water into a fluent mixture and then drains the mixture via the outlet. This process needs repeating 2-3 times until the pouch is entirely cleaned. It was found that this washing procedure is faster, easier, more hygienic and achieves much better drainage. Notice that the whole procedure does not require detaching the pouch from the stoma.

The inventor thinks that the washing procedure can be significantly improved if the pouch had also an additional washing inlet into which the user could add water to the pouch and then drain the mixture which becomes more fluent, via the draining outlet. The reason for a need for an additional washing inlet is because the draining outlet is pointing downwards and is located at the bottom of the pouch. This arrangement complicates and hinders the washing procedure since the user has to bend the outlet upwards, open it while making sure that the discharged waste remains in the pouch when the water is filled. Next, the user has to close the outlet and keep it closed while mixing the discharged waste with the water and only then the user can re-open the outlet and drain the mixture. This washing procedure has to be repeated few times if one wants an entirely empty pouch.

However, if the pouch could have an additional inlet, i.e. a washing inlet installed at the top of the pouch (in addition to the separate abdominal inlet which remains attached to the abdominal opening all the time), then the washing procedure could be significantly simplified and eased. Pouring water into the washing inlet on top rinses, washes and drains the discharged waste more efficiently downwards through the drainage outlet. To facilitate water input the washing inlet could have a shape of a funnel, which enables to pour water into the pouch from a variety of water vessels. The washing inlet also has to have a seal to prevent accidental leakage from the pouch. The washing inlet could also enable easy expulsion of gases usually excreted from the discharged waste and accumulated in the pouch. To get rid of the gasses all the user needs to do is to momentarily open the washing inlet seal and let the gasses evaporate.

Installing a washing inlet could have additional advantages. For example, the manufacturer could install on the inlet's wall an air filter that enables to remove excess gasses discharged from the discharged waste. Usually, such filters are installed at the upper side of prevalent pouches but they become clogged with discharged waste even after a very short use. Such clogging effectively blocks the filter and renders it useless. Installing a filter on the inlet wall separates it more effectively from the discharged waste in the pouch because the washing inlet extends from the very top of the pouch.

Another advantage of the washable pouch described in this application is its very flat structure which is relatively cheap to manufacture. The pouch including the washing inlet and the draining outlet is manufactured by fusing two flat sheets of flexible material such as plastic sheets at their margins. This flat structure is not conspicuous when the user wears the pouch under the user's clothes. Other inventions described below which employ various configurations of pipes and manifolds are much more bulky and expensive to manufacture.

Other problems that are routinely encountered by users who use the pouches are skin wounds and irritations that result from the sharp edges of the adhesive layer called skin barrier which adheres the abdominal adhesive faceplate inlet to the abdominal skin around the stoma. For some reason, this adhesive layer, which comprises of a disc made of adhesive material, has sharp edges on its circumference. The user could have avoided many irritations and wounds if these sharp edges would have been tapered or rounded.

3. Prior Art

Searching the PTO database for inventions which employ various means for washing pouches yielded several patents and patent applications. But all of them were entirely dissimilar to our invention. Several patent applications propose various methods for flushing ostomy pouches. In US 20080060679 Rosenberg proposes to use a special flushing water container which connects to the pouch's outlet. Rosenberg claims no water spills but since the outlet is located at the bottom of the pouch, it presents a major problem how to disconnect the container without spilling. In addition, this arrangement requires special installation in every toilet used.

In patent U.S. Pat. No. 4,692,159 Kuzemchak invents a flushing nozzle which fits the pouch's inlet and which connects to a water pipe. However, it seems that Kuzemchak forgot that this inlet is connected to the user's abdominal opening and removing the pouch when it is filled with discharged waste is almost impossible without spilling. Very similar approaches are presented in U.S. Pat. No. 6,224,581 by Withers et al. and in US 20060155152 by Walker.

In U.S. Pat. No. 6,582,410 Rutman invents an ostomy drainage apparatus which consists of a tube which connects the pouch's outlet to a large container. We fail to see how this is better than simply draining the pouch directly to a toilet bowl.

In U.S. Pat. No. 4,941,878 Petrik invented an ostomy pouch flasher which is basically a metal pipe with few holes at its end and a water pipe inlet at its other end. This pipe is designed to be inserted into the pouch and help flushing it.

In US 2006/0106354 A1 Vantrustenberge invents an ostomy pouch with 3 openings. The first one serves as an inlet which is connected to the user's abdominal opening (stoma). The second one is a wide pouch outlet which is used for pouch draining. The third opening in the pouch is a port connected to a one way valve which has a stem pipe at the valve's outlet. The third opening has two uses. The first use is for expelling gases accumulated in the pouch wherein the valve is activated by pressing the pouch and creating enough pressure which opens the one directional valve and allowing the gas to exit. The second use of the third opening is to use it for flushing the bag after draining. The stem pipe is connected to a water source and water is being forced into the pouch. This invention has two major flaws. The first one is the need for a pressurized water source that needs to be connected to the stem pipe for flushing. The second problem is a contradiction in the invention design because if the one way valve is designed to expel gasses from the pouch outwards it will block any flow of rinsing water inwards into the pouch. A similar invention is presented by King in U.S. Pat. No. 6,918,898 B2. King uses an enema bag as an irrigation water source which is connected by a tube to a plapped opening in the pouch. In our opinion, enema's dripping is much too slow for pouch rinsing and a flapped input will allow likage of gasses and waste from the pouch.

Our invention is entirely different from Vantrustenberge's because our invention does not have a valve or a pipe input. Our invention has a wide funnel inlet which allows to rinse the pouch from any water vessel, bottle or pitcher. Our inlet has also a seal which enables to seal the inlet when not in use. Expulsion of excess gases from the pouch can also be achieved simply by momentarily opening the inlet seal and sealing it afterwards.

Schena in U.S. Pat. No. 8,016,802 B1 invented a pouch irrigator which consists of a curved porous pipe (called manifold by the inventor) installed inside the pouch. Schena is manufacturing his invention under the name EZ-Clean. The irrigator has a pipe inlet installed at a pouch's opening. This invention is not practical because it requires a pressurized water source connected to the irrigator's inlet. Thus, the user can use Schena's invention only in toilets with appropriate water source. It is also very expensive solution for a disposable pouch because the manifold needs to be disposed with the pouch every few days. Another disadvantage of Schena's pouch is that it is quite bulky under the clothes. A similar pouch irrigator composed of a porous pipe installed inside the pouch was invented by Fenton in U.S. Pat. No. 4,654,037. Similar invention with pipe irrigation is in U.S. Pat. No. 7,918,836 B2 by Gill et al.

An ostomy suction system was invented by James in U.S. Pat. No. 8,167,857 B2, which uses vacuum tube connected to the pouch outlet for efficient draining.

Fundock in U.S. Pat. No. 5,470,325 invented an irrigation and venting assembly which is composed of a simple pipe inlet installed on the top of the pouch. The pipe inlet needs to be connected to a water source for rinsing.

An ostomy bag cleaning apparatus is described in U.S. Pat. No. 5,503,633 by Saunders. The apparatus is actually a drainage construction which enables to flush used ostomy pouches with a water sprinkler over the toilet. Similar approach to pouch cleaning is in US 2006/0237039 A1 by Sarvis. An peelable ostomy bag which can be cleaned by peeling it from the abdominal opening is invented by Pedersen et al. in US 2009/0163885 A1.

In summation, our invention is entirely different from all the inventions described above because our invention does not have a valve or a pipe input. Our invention is the only one which has a wide funnel inlet which allows to rinse the pouch from any water vessel, bottle or pitcher. Our inlet is flat and an integral part of the pouch. It has also a seal which enables to seal the inlet when not in use. Expulsion of excess gases from the pouch can also be achieved simply by momentarily opening the inlet seal and sealing it afterwards. In addition our invention presents the only solution to an inlet and a pouch with flat structure which is not bulky and quite cheap to manufacture.

BRIEF SUMMARY OF THE INVENTION

The present invention pertains to a novel pouch structure which enables easy washing and draining of ostomy pouches without detaching the pouch from the user. Usually, ostomy pouches are made of flexible material such as plastic and have an inlet opening which is attached to the abdominal opening of the user. The pouch accumulates the discharged waste excreted from the abdominal opening. Every few hours the pouch is filled and needs to be drained. Usually pouches have an outlet from which the pouch is being drained. This outlet is sealed most of the time when discharged waste is being accumulated and can be opened for drainage and re-sealed afterwards. When the user drains the pouch, the user has to open the outlet and to squeeze the pouch in order to force out the discharged waste. Users are experiencing a major difficulty in such draining process since the discharged waste is highly viscous and sticks to the pouch walls, Large portions of the discharged waste still remain in the pouch even after a lot of squeezing. Few inventions (described in the previous section) propose to improve the drainage by mixing the discharged waste with water, which converts it to more fluent mixture that can be easily drained. These inventions propose to add water to the pouch via various structures of pipe inlets installed in the pouch. There are two major problems with these approaches which renders them impractical. Firstly, pipe inlets need to be connected to a water source via a flexible pipe, This requirement limits the usage of such pouches only to special toilets with a water source and fitting pipes. Since most toilets are not equipped with such water sources, users of pouches with pipe inlet can use them only in few locations. Even more serious problem arises from the requirement to include in each pouch an inner pipe with a pipe inlet. Adding a pipe structure to each pouch makes it quite bulky and expensive since ostomy pouches need to be replaced with new ones every few days.

The present invention proposes an economical and efficient solution to draining and washing pouches by adding an additional washing inlet at the top of the pouch. This solution is quite economical because this inlet is made of the same flexible material as the rest of the pouch and has the same sealing arrangement as the pouch's outlet. The invention also enables efficient drainage and washing because it does not require any special water source and the inlet, which has a funnel shape can be filled from a variety of water vessels and containers. Since the proposed inlet is located at the top of the pouch and the drainage outlet is located at the bottom of the pouch, the washing and rinsing process is quite efficient. To facilitate water input, the washing inlet has a shape of a funnel. It is also equipped with a seal to prevent accidental leakage from the inlet.

The washing inlet could also enable easy expulsion of gases usually excreted from the discharged waste and accumulated in the upper part of the pouch. To get rid of these gasses all the user needs to do is to momentarily open the washing inlet seal and let the gasses evaporate.

Another advantage of the washable pouch described in this application is its very flat structure which is relatively cheap to manufacture. The pouch including the washing inlet, the abdominal inlet and the draining outlet is manufactured by fusing two flat sheets of flexible material at their perimeter margins. The sheets have identical two dimensional shapes except for an opening in the rear sheet for the abdominal inlet. The two dimensional shape of the sheets includes central area for the pouch main cavity and two bulges which extend from the central area for the washing inlet and the draining outlet. The sheets are fused all along their margins along their perimeter and the only places the sheets are not fused are short perimeter segments located at the openings necessary for the washing inlet and the draining outlet. The pouch's flat structure is not conspicuous when the user wears the pouch under the user's clothes. Other inventions which employ various configurations of rinsing pipes are much more bulky and expensive in manufacturing.

DETAILED DESCRIPTION OF THE INVENTION AND DRAWINGS

FIG. 1 describes a rear view of an embodiment of the washable pouch 1A. The rear flexible sheet 1F is illustrated with the abdominal inlet coupling 2B and the abdominal inlet opening 2A. The abdominal inlet coupling 2B which surrounds the abdominal inlet 2A has a special multi-ring profile which snugly fits the multi-ring profile of the abdominal adhesive faceplate coupling 8A (shown in FIG. 2). The rings 2B and 8A form a secure, watertight coupling when put together which enable the user's discharged waste to flow from the stoma to the washable pouch without any leakage. This coupling can be detached by pulling the rings 2B and 8A away from one another. However, the user does not need to detach the coupling when the pouch is washed. The abdominal inlet coupling 2B has two eyelets 2C which can be used to fasten the washable pouch more securely to the user's abdomen. At the bottom of pouch 1A is an outlet 1B for draining the accumulated discharged waste. The draining outlet 1B can be sealed by the seal 1C by folding the two 1C Velcro strips together one against the other. The pouch has also a washing inlet 3A, which is installed at the top of the pouch 1A. The washing inlet 3A has a shape of a funnel which facilitates pouring water into the pouch 1A. The washing inlet 3A also has a seal 3B which enables to seal it when not in use by folding together the two strips 3B which have a Velcro cover. In addition, the washing inlet 3A also could have an optional air filter 3C, which is installed at an opening in walls of the washing inlet 3A. The rear flexible sheet 1F is fused to the front flexible sheet 1E all along its perimeter margins 1D except for two short segments for the opening of the washing inlet 3A and the draining outlet 1B opening. The fused strip 1D is shown as a wide hashed line. The sheets 1E and 1F have an identical two dimensional shapes except for the abdominal inlet opening 2A in 1F. The central area of the two dimensional shapes 1E and 1F has two bulges 1B and 3A for the draining outlet and the washing inlet respectively. The side view cross section in FIG. 1 shows that the central area of the pouch has a cavity 1G which is formed between the two sheets 1E and 1F. The cavity 1G provides the pouch with a space for discharged waste accumulation.

FIG. 2 illustrates the front view and the side view cross section of the abdominal adhesive faceplate 8B. The faceplate 8B is attached to faceplate coupling 8A which has a shape of a multi-ring profile which snugly fits the multi-ring coupling 2B which is a part of the abdominal inlet coupling of the washable pouch. The faceplate 8B has a shape of a disk. The faceplate 8B has on its proximal side (body side) an adhesive layer of skin barrier 8C surrounding a central opening 8G for the stoma. The adhesive layer of skin barrier 8C is designed to adhere to the user's abdominal skin around the stoma. The adhesive layer of skin barrier 8C has a tapered circumference 8F designed to reduce abdominal skin irritation caused by sharp edges of the adhesive layer of skin barrier 8C. A flexible circular strip 8D is attached to the circumference of the faceplate 8B. The flexible circular strip 8D has a glue layer 8E which is designed to adhere the faceplate circumference to the abdominal skin and to strengthen the faceplate adherence provided by the adhesive layer of skin barrier 8C to the user's abdominal skin.

FIG. 3 illustrates the front view of an embodiment of the washable pouch 1A. The front flexible sheet 1E has two bulges 3A and 1B for the washing inlet 3A and for the draining outlet 1B. The front flexible sheet 1E is fused all along its perimeter 1D to the rear flexible sheet 1F except for two short segments for the washing inlet 3A opening and the draining outlet 1B opening. The fusing strip 1D is shown as a wide dark line as well. The washing inlet 3A has a seal 3B which enables to block all flow through the washing inlet when the seal 3B is sealed by folding its two Velcro strips 3B one against the other. Similarly, the draining outlet 1B has a seal 1C which enables to block all flow through the draining outlet 1B when the seal 1C is sealed by folding its two Velcro strips 1C one against the other.

FIGS. 4-8 describe a proposed draining and washing procedure using the drainable and washable pouch 1A. In order to illustrate the different states of contents within the washable pouch during washing and draining, FIGS. 4-8 show the washable pouch as if it was made of transparent sheets 1E and 1F. FIG. 4 describes the pouch 1A in the accumulation phase when both the draining outlet 1B and the washing inlet 3A are sealed and the discharged waste 5A which is excreted from the user's abdominal opening via the abdominal inlet 2A is accumulated in the pouch 1A.

When the user decides to drain the pouch 1A, the user opens the seal 3B of the washing inlet 3A and pours water 4B into the inlet 3A from the pitcher 4A. This step is illustrated in FIG. 5. The amount of water 4C which is poured from the pitcher 4A should be sufficient to create a fluent mixture with the accumulated discharged waste 5A in the pouch 1A. The seal 1C of the draining outlet 1B is sealed during this phase.

As illustrated in FIG. 6, the user then seals the washing inlet 3A and squeezes the pouch 1A with the user's hands 6 several times until the water mixes with the discharged waste and creates a fluent mixture 5B. The squeezing and mixing step is described in FIG. 6. The seal 1C of the draining outlet 1B remains closed at this phase.

In FIG. 7, the user opens the drainage outlet seal 1C and drains the mixture 5B into the toilet bowl 7. The washing inlet seal 3B remains closed at this phase. FIG. 8 describes the state of the washing pouch 1A after drainage is completed. The drainage outlet 1B and the washing inlet 3A are sealed by seals 1C and 3B respectively. At this stage the pouch is ready for the next discharged waste accumulation.

In our experience, almost all the discharged waste mixture 5B is drained at the first washing. If some discharged waste still remains in the pouch 1A, the user can repeat the washing procedure until the pouch is completely emptied.
